Abstract

PURPOSE:To remove resonance of a dome and to improve an acoustic pressure frequency characteristic, by packing the dome of a loudspeaker of which an edge and the dome are formed to one body, with a high loss material such as fine glass wool. CONSTITUTION:An air chamber 10 in a dome 2 of a loudspeaker consisting of an edge 1 and the dome 2 which have been molded to one body by resin is packed with a high loss material 14 such as fine glass wool. According to this constitution, Q of resonance is suppressed low by damping the compliance of the dome 2 by the high loss material 14.
